* 您早 (nín zǎo): This is a more polite and respectful way to say good morning, especially to someone older or in a position of authority. It literally translates to "you early."
Informal:
* 早 (zǎo): This is a very casual and common way to say good morning, often used between friends and family. It literally translates to "early."
Other options:
* 早上安好 (zǎoshang ān hǎo): This is a more literary way to say good morning, meaning "May your morning be peaceful."
* 早晨 (zǎochén): This is another way to say "morning," but it's not used as a greeting as often as "早上好."
